"I give everything to you."
Translation:Tugaim gach rud duit.
Duolingo is designed to teach An Caighdeán Oifigiúil. As a courtesy to people who are more familiar with one of the regional dialects, a vast amount of additional work was done to add non-Caighdeán responses as alternative answers. Use the Report flag and submit "My answer should be accepted" to request that your answer be added as an alternative answer.
I don't think Duolingo has any exercises with mise or tusa either, but they are all emphatic or contrastive forms of the pronouns, and very widely used. Here are some examples using duitse from the NEID - I've used bold to indicate that you are emphasising the you in these expressions:
"what's it to you?" - cén gnó duitse é?
"this email is for your eyes only" - duitse amháin an ríomhphost seo
"my door is always open for you" - bím i gcónaí ar fáil duitse
"it's easy for you to talk" - is éasca duitse bheith ag caint
(The NEID doesn't do "literal" translations, as they aren't very useful in many cases).
